Think of the letter 'a' to represent 1 apple.
a = 1a = 1 apple
2a = 2 apples
3a = 3 apples
and so on
Adding 7a with 4a means we have 7 apples and we add on 4 more. We'll have 7+4 = 11 apples total.
Algebraically we write 7a+4a = 11a to do this using shorthand.
The 9-7 portion is calculated like you'd expect and it simplifies to 2.
------------
Here's what the step by step picture looks like
(7a+9) + (4a-7)
7a + 9 + 4a - 7
(7a+4a) + (9-7)
11a + 2
Answer:
The correct option is B
B) Stem and Leaf plot
Step-by-step explanation:
The purpose of stem and leaf plot is to show the data distribution while retaining its uniqueness. Stem and leaf plot shows the raw values by retaining the original data. It is usually recommended for batches between 15 and 150 data points.
In Stem and Leaf plot, the leaves are usually the last digit of a data, which stems are the remaining digits. For example if we have 2 number suppose 171 and 176, then in stem and leaf plot, as 17 is common, it can be the stem, while last digits of both numbers i.e 1 and 6 are leaves. It can be written as:
17 | 1 6
Answer: it is undefined for X=-9
Step-by-step explanation:
I’m assuming that you mean undefined.
A quotient will be undefined when the denominator is equal to 0.
X+9=0
X=-9
Step-by-step explanation:
Given point (4 , -8) , slope (m) = 2
Now
the equation of line is
y - y1 = m ( x - x1)
y +8 = 2 ( x -4)
y + 8 = 2x - 8
2x - 8 - 8 -y = 0
2x - y - 16 = 0
which is the required equation
